scopeopenid

Scopeopenid is not a standardized term in OpenID Connect or OAuth 2.0. It is sometimes used informally to describe the practice of including the openid scope in an authorization request or to refer to the combination of scope elements needed to perform an OpenID Connect authentication. There is no official separate scope called “scopeopenid,” and proper documentation typically treats it as a shorthand rather than a distinct protocol feature.

In OpenID Connect, the scope parameter specifies the level of access and identity information requested. The presence of the openid scope is required to initiate an OpenID Connect flow and obtain an ID Token. Additional scopes such as profile, email, or address request specific claims about the user, typically delivered through the UserInfo endpoint. A typical request might include scope=openid profile email, along with other standard parameters.

Common flows that use the openid scope include the Authorization Code Flow and the Hybrid Flow, often with PKCE for public clients. The authorization response may yield an authorization code (and optionally an ID Token) that a client exchanges at the token endpoint for access tokens and an ID Token. The ID Token contains claims about the user and the authentication event, and it should be validated for issuer, audience, expiration, and nonce.

Security considerations include always validating ID Tokens, using nonce values to mitigate replay, protecting redirect URIs, and employing TLS. Proper handling of consent, state parameters, and token storage is essential. Scope management, including the minimal necessary scopes, helps reduce exposure of user data.
